      What's the matter with air conditioning and cooling without heating

      What's the matter with air conditioning and cooling without heating 1.First, it may be because the vents of the indoor unit and outdoor unit are blocked by something, or a lot of dust has accumulated on the filter inside the air conditioner; 2. It may be because the heat blown from the air conditioner is seriously lost; 3 2. It may be because the amount of refrigerant in the air conditioner is too small, which leads to a great reduction in the heat exchange efficiency, so that the air conditioner does not heat. <img src="{{media url=&quot;magefan_blog/What_s_the_matter_with_air_conditioning_and_cooling_without_heating3.jpg&quot;}}" alt="" />
